Mathematical writing involves a lot of special symbols, equations,
matrices, pictures and such things which are not easy to create
in usual wordprocessing software. Moreover, many mathematicians
(myself included) feel that the equation editors included with e.g.
Microsoft Word and such are inadequate and produce unsatisfactory
results.
Happily, you can produce professionalquality mathematical documents
yourself with the industrystandard mathematical typesetting software
for free! Real mathematics is written in a typesetting language known
as LaTeX, pronounced "laytek" or "lahtek" (but never "laytex"). LaTeX
is not a word processor but rather a typesetting language similar in some
ways to HTML; documents have a header section and body section, for instance,
and most formatting uses "begin" and "end" tags. You use your favorite text
editor to write the LaTeX source code in a file ending with a ".tex". Next,
you compile the source code into a .pdf file using a program called
"pdflatex." Any picture files you want included will need to be in the
same directory as your .tex file as either .png files or .pdf files.
The tools you will need to produce professionallooking mathematical
writing are all free software, though if you're determined to pay there
are commercial packages available, e.g.
Scientific
Workplace and
others. To
get LaTeXing, you'll need:
 A text editor such as Notepad, TextEdit, or
emacs, and
 The LaTeX compiler software. If you're using Microsoft Windows, you'll
want to download the latest version of MiKTeX;
for MacOS, the simplest option is to install
MacTex;
for Linux, you'll want to install the "texlive" package using your favorite
package installer (e.g. aptget, synaptic, rpm etc.)
 Alternatively, there are free integrated LaTeX environments which
include both a LaTeX compiler and a custom text editor, such as
Kile,
Lyx and TeXshop.
 To make diagrams, I recommend the GIMP
and/or Inkscape, both of which are
free and available for Windows, MacOS and Linux.
 You can also draw images in LaTeX itself using macro packages
like PGF and TikZ or
LaTeX's native picture environment
 If you want to make presentations for giving talks, the
Beamer package
is included with most LaTeX distributions, but can be downloaded separately
if needed.
To learn the LaTeX typesetting language, the usual thing is to start with a
sample document like this one and play with it
to see how it works. There are also excellent LaTeX manuals which will walk
you thorough the features of the language from the basic to the obscure. A
freely downloadable reference guide is here,
while the canonical guide is here. Many more examples are available at texample.net.
